[Machine] I heard the Prophet (pbuh) mentioning "the place from where sweat flows from the son of Adam." One of them said, "It goes to the fatty part of his ears." The other one said, "It is restrained by the sweat gland." Ibn 'Umar pointed towards his ears and drew a line with his index finger between the fatty part of his ear and his temple.
سَمِعْتُ النَّبِيَّ ﷺ يَذْكُرُ «مَبْلَغَ الْعَرَقِ مِنِ ابْنِ آدَمَ» فَقَالَ أَحَدُهُمَا «إِلَى شَحْمَةِ أُذُنَيْهِ» وَقَالَ الْآخَرُ «يُلْجِمُهُ الْعَرَقُ وَأَشَارَ ابْنُ عُمَرَ فَخَطَّ بَيْنَ شَحْمَةِ أُذُنِهِ بِالسَّبَّابَةِ»
